GMC has announced a new vehicle feature to help prevent caregivers from accidentally leaving children in cars, which can be a fatal mistake in hot weather. GMC’s “Rear Seat Reminder” is an industry-first technology intended to help remind the driver to look in the rear seat before exiting the vehicle under certain circumstances.

GMC’s protective feature will be standard in the new 2018 GMC Terrain. The technology does not actually detect objects or people in the rear seat but monitors rear door usage for up to 10 minutes before or during a trip, and when the driver turns off the vehicle. An alarm sounds five chimes and displays a warning on the driver information center screen, prompting a second look in the back seat. A GMC staff engineer and mother of two, Tricia Morrow, led the development of the technology.

It is as tragic statistic that about half of the heatstroke deaths of children under age 14 occur because caregivers mistakenly leave children in cars. Since 1998, more than 660 children across the United States have died from heatstroke when unattended in a vehicle. During September’s back-to-school season and Baby Safety Month, Safe Kids Worldwide warns that changes in caregivers’ routines can lead to children being forgotten in cars.

Young children are particularly at risk as their bodies heat up three to five times faster than an adult’s. When a child’s internal temperature gets to 104 degrees, major organs begin to shut down. And when that child’s temperature reaches 107 degrees, the child can die.

Safe Kids Worldwide, an organization of 400 coalitions across the U.S. and funded by General Motors, developed a system called ACT to help remind caregivers not to leave children in cars. The acronym focuses on avoiding heatstroke by never leaving a child in a car, creating reminders that a child is riding in the car, and taking action by calling 911 if a child is left alone in a car.

Safe Kids warns that children get left behind by loving, caring parents simply because they become distracted, and that these accidences are more common with new parents who are sleep-deprived or when a parent’s routine is disrupted.
